ZWY-322B Single-Layer High-Capacity Orbital Shaker

Overview

The ZWY-322B Single-Layer High-Capacity Orbital Shaker is an industrial-grade laboratory shaker engineered for continuous, stable, and reproducible orbital motion in controlled environmental settings. Designed specifically for high-throughput applications in bioprocessing and life science research, it operates on the principle of eccentric-driven orbital oscillation—generating uniform circular motion (Φ35 mm orbit) across a single large-format platform (920 × 640 mm). Unlike reciprocating or linear shakers, this unit delivers consistent shear profiles ideal for aerobic microbial culture, suspension cell propagation, enzyme kinetics assays, and scalable fermentation studies where homogeneous mixing and gas exchange are critical. Its natural convection thermal management system enables integration into standard incubator rooms or climate-controlled laboratories without active air circulation—making it compatible with ambient temperature operation between 5 °C and 50 °C. The brushless AC induction motor ensures long-term reliability, zero maintenance, and precise speed regulation across its full 30–300 rpm range (±1 rpm accuracy), while the soft-start acceleration algorithm minimizes mechanical shock to sensitive biological samples during initiation.

Key Features

• PID-based microprocessor controller with real-time environmental scanning for adaptive speed and timing stability
• Backlit LCD interface displaying setpoints and live parameters—including speed, elapsed time, remaining timer, and operational status
• Parameter encryption function to prevent unauthorized modification of critical operating conditions—supporting lab SOP compliance and audit readiness
• Non-volatile memory retention for all user-defined configurations, eliminating repetitive setup between experiments
• Extended programmable timer (0–500 hours) with automatic termination and dual-mode alarm (audible + visual)
• Intelligent power-failure recovery: resumes prior operation sequence upon grid restoration, preserving experimental continuity
• Heavy-duty structural architecture using precision-cast aluminum and reinforced cast iron components for vibration-damping rigidity
• Electrostatically applied powder-coated steel enclosure for corrosion resistance and cleanroom-compatible surface integrity
• Optimized mechanical balance achieved via one-piece machined platform assembly—ensuring minimal runout and long-term rotational fidelity

Sample Compatibility & Compliance

The ZWY-322B accommodates standard and custom-sized culture vessels including Erlenmeyer flasks (up to 5 L), Fernbach flasks, baffled bottles, and multi-well plates mounted on universal clamps or silicone matting. Its orbital motion profile meets the mechanical requirements specified in ISO 20737:2021 (Laboratory equipment — Shakers — Performance requirements and test methods) and supports workflows aligned with USP , ASTM E2500-13 (Good Manufacturing Practice for Pharmaceutical Equipment), and FDA 21 CFR Part 11 when integrated with validated data capture systems. While the unit itself does not include built-in data logging, its parameter-locking and memory functions facilitate GLP/GMP-aligned documentation practices by ensuring configuration consistency across shifts and operators.

Software & Data Management

The ZWY-322B operates as a standalone hardware platform with no embedded software stack or network connectivity. All control logic resides within the dedicated PID microcontroller, minimizing firmware vulnerabilities and eliminating dependency on external OS platforms. For regulated environments, users may integrate third-party USB or RS-232 data loggers compliant with 21 CFR Part 11 Annex 11 requirements to record speed, duration, and event timestamps. Parameter encryption and password protection align with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate), supporting traceability in quality-controlled biomanufacturing and academic research labs subject to institutional review or regulatory inspection.

Applications

This shaker serves as a core platform in upstream bioprocess development, particularly for strain screening, seed train expansion, and small-scale bioreactor mimicry under non-sterile or semi-sterile conditions. It is routinely deployed in pharmaceutical QC labs for dissolution testing preparation, in academic molecular biology labs for plasmid amplification and protein expression cultures, and in food safety testing facilities for enrichment protocols per ISO 6579-1. Its robust torque delivery at low speeds (e.g., 30–60 rpm) supports delicate tissue dissociation protocols, while high-speed capability (250–300 rpm) enables rapid oxygen transfer in high-density yeast or bacterial fermentations. The large deck area also permits parallel processing of heterogeneous vessel types—enhancing experimental throughput without compromising mechanical consistency.

FAQ

What is the maximum flask size supported on the ZWY-322B platform?
Standard configuration accommodates up to five 5-L Erlenmeyer flasks or equivalent volume in standardized culture vessels; load distribution must remain balanced within ±10% mass variance across the platform.
Does the unit comply with electromagnetic compatibility (EMC) standards for laboratory use?
Yes—the device meets IEC 61326-1:2013 Class B emission limits for laboratory equipment and includes internal filtering to minimize conducted and radiated interference.
Can the ZWY-322B be installed inside a CO₂ incubator?
No—its natural convection design and lack of sealed enclosure make it unsuitable for humidified or CO₂-enriched atmospheres; it is intended for ambient-temperature room installations only.
Is calibration certification available for speed and timer accuracy?
Factory calibration reports (traceable to NIST standards) can be provided upon request; users are advised to perform periodic verification using ISO 20737-recommended tachometric and chronometric methods.
What maintenance is required for long-term operation?
None beyond routine cleaning of the platform surface and inspection of mounting hardware; the brushless motor and sealed bearings require no lubrication or scheduled replacement over its rated service life (>20,000 hours).
